Linux how to change booting options without pressing TAB

[Cally725]

Hi,

I would like to completely automate my Linux installation with Kickstart. However I need to press on TAB when the GRUB menu appear to specify the name of my Kickstart file.

Is there a way to specify the Kickstart name in the vbox file to avoid having to press the TAB key.

More info...

I boot from an iso mounted on the optical IDE port.

For instance when starting the VM, the CentOS menu appears like this:

CentOS Linux 7

Install CentOS Linux 7
Test this media & install CentOS Linux 7
Troubleshooting

Now if I press <TAB Key> I get the following line at the bottom of the screen:

>vmlinuz initrd=initrd.img inst.stage2=hd:LABEL=CentOS\0x207\x20x86_64 quiet

I need to change this line to:

>vmlinuz initrd=initrd.img ks=path_to_cfg_file.ks.cfg

How can I do that without having to manually intervene ?

Thanks for your help.

You're talking about actively intervening with a guest OS, one for which you don't have any control. You simply can't.
